Have you recently had a new furnace put in and are now experiencing an unusual smell? You’re not alone, because plenty of other homeowners also have this happen at first. Let’s review what’s creating this smell, and when you can expect it to subside, as well as three other furnace smells you shouldn’t disregard.
Why Your New Furnace Smells
There are two explanations why a new furnace might smell.
Your furnace has a special coating on certain parts to keep them from rusting. This may include the heat exchanger, which safely exhausts gases including carbon monoxide naturally produced during the heating process.
When your furnace starts for the first couple of times, the coating may emit a burning smell. This is normal and the smell should dissipate the more your furnace runs.
To be on the safe side, you’ll want to contact a heating and cooling company if the smell continues. A burning smell that lingers can mean the motor is too hot or there’s an electrical problem, among other problems.
Dust accumulates inside your furnace when it’s off in the summer. That dust will burn off when you switch on your furnace in the fall, creating a burning smell. This smell should disappear within a few minutes.
One way you can decrease or prevent this smell is by having furnace maintenance done every single year. This is necessary to keep your valuable manufacturer’s warranty good, plus it keeps your furnace clean and ensures it will run smoothly during the upcoming heating season.
3 Other Furnace Smells You Shouldn’t Dismiss
While it’s less common for a new system to necessitate furnace repair, it can happen. Here are three other odors you should watch for and what they might mean.
- Burning plastic or rubber. If your furnace smells like burning plastic, you might have an electrical problem. Electrical wiring is coated in plastic to avoid shocks, and this smell is a sign that heat is melting this preventive coating. To avoid a fire, switch off your furnace immediately and have it checked out by an HVAC technician.
- Gas or rotten eggs. Gas companies include sulfur in natural gas to signal you when there’s a leak. If your furnace smells like gas or rotten eggs, shut it off as soon as possible, get out of your home and dial 911. Exposure to natural gas can make you ill, plus it’s highly flammable and explosive.
- Musty. If your furnace smells musty, you might have mold and mildew growing in your ductwork. We advise having your ductwork checked and cleaned if necessary.
